The parents of the children who fired the shots are to be blamed for this incident. If parents keep firearms within the reach of children instead of keeping them in secured places this incident would not have occured. The parents of both the children should be arrested immediately and send to prison for at least five years for gross negligence. Most builders have very shaddy backgrounds so they have to keep firearms to protect and threaten people. So while admitting children of builders the school authorities should enquiry about the backgound & past records of such bulders before admitting their children. Thus the school is also to be blamed for this incident.----Ajit
